United States Patent ROOFING CONSTRUCTION John H. Goodwin, Greensburg,Pa., assignor to Overly Manufacturing Company, Greensburg, Pa., acorporation of Pennsylvania Application February 7, 1955, Serial No.486,366

2 Claims. (Cl. 108-21) This invention is for an improvement in roofingand relates particularly to a batten type of roofing in which theroofing sheets at their edges have a water-tight engagement with thebatten.

The invention is for an improvement in roofing of the general typedisclosed in my prior Patent No. 2,447,065, granted August 17, 1948. Inmy said patent there is disclosed a batten type of roofing in which theedges of the roofing sheets are bent up along the sides of a battenwhich extends down the slope of the roof, and there is a cap strip whichserves to clamp the edges of the sheets to the sides of the batten.

The principal object of the present invention is to provide a roofconstruction of this type in which the batten is formed of metal, and inaddition to forming a waterproof connection between the batten and theroofing sheets, also provides an entirely waterproof connection betweenthe batten and the roof structure preventing entrance of the waterflowing over the roof into the structure upon which the batten ismounted.

In the drawings forming part of this disclosure:

Fig. 1 is a longitudinal vertical section through the batten portion ofa roof constructed in accordance with my invention;

Fig. 2 is a transverse vertical section taken along the lines II-II ofFig. 1; and

Fig. 3 is a transverse vertical section taken on the lines IIIIII ofFig. 1.

In the drawings, reference character 2 designates a roof support whichmay be of concrete, structural metal, wood, or any other materialcommonly used for the roofing structure of a building. Mounted on theroof support are a plurality of battens 3, only one of which is shown inthe drawings, all others being of similar construction. These battensextend up and down the slope of the roof. They are formed with twoupwardlyextending side flanges 4 and 5 connected at their base 'by amember 6 which extends continuously between and beyond each flange 4 and5. At each side of the said flanges the member 6 has slotted openings 7therein through which extend the fastening members 8 securing the battento the roof structure. Intermediate the vertical dimension of eachflange 4 and 5 is an inwardlyextending substantially horizontal flange 9terminating in an angularly-disposed flange 10. These flanges 9 extendlongitudinally of the length of the batten and their flanges 10 aredisposed in horizontally spaced relation. Mounted on the batten flanges9 and 10 are a plurality of members 11 having at each side thereofsuitably shaped inwardly-extending openings to receive the ends of thebatten flanges 9 and their associated flanges 10 so that the members 11are slidable thereon longitudinally of the batten. At substantially thecenter line of the batten, each member 11 has a tapped opening extendingtherethrough for reception of a screw-threaded fastening member. Thesebattens may be of relatively light weight metal and are mosteconomically made of an extruded metal such as aluminum, brass, or anyother suitable metal.

The roofing sheets are designated 13. They have their edges turnedupwardly to provide substantially verticallyextending flanges 14disposed adjacent the preferably slightly diverging upwardly-extendingbatten flanges 4 and 5. The upturned roof flanges 14 each have an,

inwardly-turned lip 15 extending therealong, these lips hooking over andoverhanging the top of the flanges 4 and 5 as clearly shown in thedrawings.

There is a cap strip or cover strip 16 having downwardly-extendingflanges 17 that fits over the batten so as to be supported thereon andthe flanges 17 embrace the upturned edges 14 of the roof sheets. Atsuitably spaced intervals longitudinally of the length of the cap stripare suitable openings for reception of a threaded fastening member suchas a machine screw 18, the shank of which extends inwardly of the capstrip and is engaged with the tapped opening in the member 11 slidablymounted upon the batten flanges 9 and 10.

In assembling the roof, the battens 3 are first secured to the roofstructure by the fastening members 8 extending through the elongatedopenings 7 in the member 6 of the batten. In those cases where the roofis laid across structural members or concrete having preformed openingstherein for reception of the fastening members,

the elongated openings 7 permit slight adjustment necessary to admitmatching up with such preformed openings. The roof sheets are then putdown. Usually the flanges 14 will have been formed in advance and thelips 15 will also usually have been formed in advance. After the roofsheets have been put in place the cap strip 16 is fitted into positionand the fastening members 18 extending through the cap strip 16 areengaged with the members 11 mounted within the batten. As clearly shownin the drawings, as the cap strip is fastened in position it forces thelips 15 of the roofing sheets into engagement with the tops of thebatten flanges 4 and 5 forming a waterproof seal. The flanges 17 of thecap strip 16 embrace the flanges 14 of theroofing sheets, forming atight joint or connection therewith.

The construction herein disclosed and described is thoroughlywater-tight because any wind-driven rain or melted snow which may bedriven up the vertical surfaces of the flanges 14 of the roofing sheetswill drop off the downturned lips 15 of the roofing sheets into thegutter formed by batten flanges 4 and 5 and bottom member 6 so as todrain out longitudinally at the lower end of the batten. Should anywater leak in under the heads of the screws 18 and run down thesescrews, such water will also fall upon the member 6 of the batten anddrain out longitudinally at the lower end of the batten. The fasteningmembers 8 securing the batten bottom member 6 to the roof structure aredisposed up wardly of the batten flanges 4 and 5, and beneath the roofsheets 13 so that no water reaches these fastening members, and hencecannot leak in around the fastening members into the buildingstructures. The elongated openings 7 through which the fastening members8 extend also provide for relative movement between the batten members 6and the member 8 during expansion and contraction of the batten.

While I have shown and described one particular form of my invention, itis to be understood that this is the present preferred form and thevarious details of construction are for purposes of illustration and notlimitation except as made necessary by the scope of the appended claims.
